PICK.

SPECIFICATION forming part of Letters Patent N0. 659,101, dated October 2, 1900. Application filed March 26, 1900. Serial No. 10,303. (No model.)

To all whom it may concern:

Be it known that we, ISAAC PRICE and JOHN OMEALIA,citiZens of the United States, residing at Sherrard, in the county of Mercer and State of Illinois, have invented certain new and useful Improvements in Picks; and we do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in implements known as mining-picks, especially for working coal-mines.

It has forits object,principally,to effectively fasten or secure the pick in place; to prevent the accidental catching or striking of the fast-ening therefor against or upon the sides or walls of the coal-ban k, which would tend to displace or unfasten the same, and to greatly simplify construction, lessen cost of manufacture, and facilitate the assembling and securing of the parts together.

It consists of the combination and arrangements of parts substantially as hereinafter more fully disclosed, and specifically pointed out by the claim. v v

In the accompanying drawings, illustrating the preferred embodiment of our invention, Figure 1 is a side view. Fig. 2 is a central section taken in the plane of the handle. Fig. 3 is a section at right angles to the plane of the aforesaid section, with parts broken away.

Latitudeis allowed herein as to details, as they may be changed without departing from the spirit of our invention and the same yet remain intact and be protected.

In carrying out our invention we provide the pick 1, of suitable construction for the kind of work to be done,with a central opening or eye 2, and around the outer end of said opening is a circular recess or countersink 2. A ferrule or socket 3, adapted to receive and have suitably secu red thereto the handle 4, has one end preferably more or less flared and presented toward the side of the pick in alinementwith the eye or opening 2. A screw-threaded bolt 5, having, preferably, an unthreaded or plain portion and at one end a circular flange 5, is adapted to engage or let into the recess or countersink 2 in the pick, the end of the bolt thus being brought flush with the surface of the pick and prevented from projecting beyond it. It is thus so disposed to avoid contact with or striking against the sides or walls of the coal-bank, which would tend to turn it finally out of its locking position and permit the accidental detachment of the pick.

The bolt 5 is inserted into or through the pick,with its head let into the recess or countersink 2 thereof and screwed into a screwthreaded passage 6 of the ferrule or socket 3, its inner angular end having a transverse passage or hole 7 opening through each of its sides to receive a handspike or lever for screwing the bolt home and firmly tightening the parts together.

In order to permit the engagement of the actuating or manipulating handspike or lever with the screw-bolt 5,the ferrule or socket 3 is provided with a lateral opening 8 to receive said handspike or lever alining with the inner end of said screw-bolt. Thus it will be seen that the use of nuts, keys, or wedges is obviated and that our fastening comprises, substantially, but a single separate part, as above disclosed.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is

A tool of the character described comprising the pick, proper, having a countersink or recess in its forward edge, a handle-socket piece having a threaded passage opening through its forward end, a transverse passage communicating with said threaded passage and opening laterally through said socket,and a handle-receivin g socket,wit-h animperforate partition between said socket and transverse passage, and a screw-bolt, with its head let into the recess or countersink of said pick and having a reduced angular end terminal with handspike-receiving apertures or holes opening through the respective sides thereof, substantially as specified.

In testimony whereof we affix our signatures in presence of witnesses.
